Guys, I'm sure this has been asked before! Just picked up an 05 Zetec Climate with the 6000CD stereo. The clock is an hour ahead and the date wrong, everytime we reset it manually as soon as we turn off the ignition it goes back to an hour ahead!! Read somewhere that it might need an ECU update? Is this just for the radio or instrument cluster? Also the headlights have quite a bit of condensation in them, is this normal? Any help great received. Cheers Dazza
